How to choose sunglasses
Material shall be a primary criterion in choosing sunglasses, because health is more important to the style or image. Glasses not only help protect your eyes from bright sunlight, but also do not allow UV light (only glasses with glass lenses). Just wanted to say that too small glasses (whether glass or plastic) though will look stylish, but will be a poor tool in sun protection.

Sport, recreation and sunglasses
For sports sunglasses special requirements. They not only must reliably protect your eyes from the sun, but have increased strength, to be made of special plastic, not glass, because glass increases the risk of eye injuries. According to statistics, 90% of eye injuries could be prevented if protective eyewear, with nearly half of all injuries occurring in children under 14 years.

How to choose glasses for a child?
In the first year of life, the main indications for correction are aphakia and high myopia. In children under the age of three leading indications for correction of hyperopia is for esotropia. Preschool children (3-7 years) to correct aphakia, congenital myopia and hyperopia are added early acquired myopia and astigmatism. At school age, the leading indication for the correction of myopia is acquired.

How to pick the right rims of the glasses?
New Year - the right moment to change the old, familiar, or start something new. For example, you can radically revise its image, or even just thinking about it. Think we'll start with the principal, and most importantly to us, loved ones, of course, the eyes, and everything associated with them.

What you need to remember when choosing a frame for glasses?
Participation points is a fairly serious procedure. Many people, especially women, are choosing to purchase the frames as a costume or decorations. The frame should be modern, "trendy" and yet have to face, color and styling your hair, and jewelry.

Improving appearance points lenses
Vysokoprelomlyayuschie lenses made of organic materials can significantly improve the appearance of spectacles. Using the lenses of materials with refractive indices from 1.60 to 1.74 can substantially reduce the thickness and weight of lenses and glasses to make a superficially more attractive, even at high degrees of ametropia. Variety vysokoprelomlyayuschih range of lenses in combination with optical coatings, which offer today, many manufacturers, often puts consumers in a quandary: what lens to choose? To make the right decision, we must understand the basic characteristics and features of the lens material with high and superhigh refractive index.

Contact lenses
It is believed that the eyes of the lens blush, "dried" lacrimal gland, eyes acquire a specific shine (not the greedy, not that ravenous), triggered by a myriad of diseases and so on. I wear lenses for more than 4 years. With regard to shine in the eyes and other cosmetic effects of the MCL, then I am with my close friends spent the experiment: one in the eye lens, the other without.

Spectral points or more on computer vision syndrome
American Association of optometric studies published data on the new occupational disease "Computer vision syndrome" - (KSZ). Computer vision syndrome in one form or another is observed in 100% of computer users. His symptoms are familiar to almost everyone who holds the monitor more than 4-5 hours a day. Ophthalmologists note the rapid growth of cases of SGC. For example, in North America with typical complaints of the SGC to the doctors turned to 1992, 10 million people. In 1996 - 15 million people., And in 1998 for 22 million people.

Polarizing eyeglasses. What do they differ from ordinary sunglasses?
Although the cost of those and other quite comparable, but the fishing is desirable polarized glasses. How to check whether the data points polarizing? Very simple. Take two pair, and lean their glasses to each other. You will be able to see through them. I now turn to some points by 90 degrees. If you continue to see through the glass, then the conventional glasses, but if you do not see - that's all right - you are in the hands of polarized eyeglasses. What it does affect fishing?

Sunglasses - Accessory enigma
The bright sun is often the cause of the appearance of wrinkles. On clear summer days, it is impossible to watch without squinting his eyes, especially if it is near sea. Sunlight reflected by water, shine in mercy. The only salvation in the hot, cloudless days are the sunglasses.

Glasses computer 

By order of Minzravmedproma Russia, people with visual defects, at entry associated with computer equipment required to undergo a complete ophthalmological examination. Ability to perform such work is determined two factors: the nature of the visual defect and the severity of work. 

At the same time have identified a number of categories of workers, each with their own demands on the quality of vision. Jobs I category are not considered visually-heavy, so for workers do not impose the most stringent requirements. It is desirable that the visual acuity was not less than 0.4 diopters, so that works could freely read the text at a distance of 60-70 cm Otherwise, employers will have to change the settings work programs. 

Portfolio II category are visually-intensive. They have allowed myopia and hyperopia up to 8.0 diopters astigmatism up to 3.0 diopters, visual acuity with correction of 0,5 / 0,2. Candidates for the position with uncompensated or subcompensated glaucoma are not allowed to work. 

Tier III permits to perform work on a computer that only persons who have developed short-sightedness of not more than 5.0 diopters hyperopia - not more than 2.0 diopters, astigmatism - no more than 1.5 diopters, and visual acuity with correction - not less than 0,9 / 0,6. For staff members are busy working on the computer, as well as all those who one way or another computer pays a certain amount of time, methods of vision correction do not differ much from the total correction of refractive defects. 

Children and adolescents with myopia less than 2.0 diopters of computer glasses do not need. However, it should control the distance between children's eyes and the monitor - it should not be less than 50 cm could be more short-sightedness is needed glasses. It should be noted that work on the computer you want the optical power points was on 0,1-1,5 diopters less than for gazing into the distance. This helps reduce eye strain while working. 

For myopic adults whose activity is connected with the daily use of computer technology, glasses are required when people with difficulty reading printed text at a distance of 30-35 cm or text on the screen from a distance of 60-70 cm is very often the case that the reading impossible at both distances, so ophthalmologists prescribe glasses with bifocal lenses. 

With farsightedness, eyeglasses are usually required in cases when there is fatigue during operation, decreased visual acuity or first signs of strabismus. But children, presbyopic, eyeglasses when working on a computer must be constantly. In both cases, the selection of points made by the same rules as with myopia, that is, so that can be easily to read text from a distance of 60-70 cm
Astigmatism is sometimes difficult to monitor normal vision, therefore, also involves the use of corrective glasses. They are are called - astigmatic. As a rule, to work on your computer does not need to pick up some special lenses - if in their everyday glasses user could see and not feel discomfort, they may well be used when working with monitor. 

Age farsightedness, or presbyopia, begins with 35-40 years. At this age, most people have been declining clarity view, so when you work with closely spaced objects is needed glasses. To use the computer may need glasses slightly weaker than, for example, for reading. The rules of selection of lenses remain the same: a clear visibility of the text from a distance of 30-35 cm and 
monitor from a distance of 60-70 cm Computer glasses are usually provided with a special cover - color filter that enhances the contrast of the image. It possibly because the filter approximates the maximum color sensing images on the monitor to the spectral sensitivity of human eye, which, in turn, reduces fatigue of the optical system of the eye.
